BINDING-STRIP FOR FLQORTCOVERING.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application led February 11, 1918. Serial No. 216,592.

To aU 'whom it may concern:

Be it known that I, LUDWIG L. BLAKE, a citizen of thc United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Binding-Strips The primary object of the invention re-A sides in the provision of uniform metallic binding or securing strips for the edge margins of slabs or squares of linoleum or like floor fabrics, which are of a structure which will not readily bend or yield under the weight of persons walking thereon,v and by the use of which strips an artistic and eX- ceedingly serviceable floor covering may be made by the use of linoleum remnants or cuttings which are now mainly wasted or scrapped. A further object resides in so forming t-he securing strips that a single strip will serve to form a marginal edge binding for two adjoining squares or slabs, and which are of sufficient rigidity throughout their length to prevent distortion thereof by ordinary stresses to which same may be subjected, and by virtue of which rigidity but a. single fastening element applied to each end thereof and to the ioor pro-per will suffice to hold the strip in proper relation with respect to the slabs retained thereby.

A still further object resides in providing each end of the strips with a depression, so that the meeting ends of alined strips, as for example, the intersecting ends of four crosswise arranged strips, will jointly form a shallow socket adapted to receive a large headed nail so as not to materially or in no wise protrude above the strips, and the head of which nail will overlap and secure the end of each strip so arranged. A Still further object resides in providing the strips with mitered corner edges, so that the eX- treme ends of four 'intersecting crosswise arranged strips will be equidistant, and form an opening to permit a nail to be driven therethrough, andwith the head of the nail bearing upon substantially equal parts ofthe strip ends.

With the above and other objects in view, the invention will be described in the following speciication, reference being had particularly to the accompanying drawings, in which:

Figure l is a plan view illustrating the application of the invention.

Fig. 2 is an enlarged fragmentary sectional view taken on the line 2-2 of Fig. l.

Fig. Bis a fragmentary plan view showing the` corners of four adjoining slabs and the manner of securing same.

Fig. is a perspective view of one end of a securing strip. t

Fig. 5 is a view in elevation showing the proximate ends of alined securing strips and the fastening element therefor.

Referring now more particularly to the accompanying drawings, the referencenuf meral 5 indicates slabs or squares which may consist of any suitable material usable as. a Hoor covering, such as linoleum and the like, and, preferably rectangular in form. vThe slabs are preferably arranged upon the floor to be covered in uniform parallel rows and in relatively slightly spaced relation, with the space-s between the rows in alinement.

In order to hold the slabs in proper relative position and fixed with relation to the floor to be covered, as well as to provide a protection or binding for the marginal edge of each slab, I provide metallic strips 6, preferably and approximately of a length corresponding to the edge length of the slabs, and substantially T-form in cross section, the web portions 7 of which are disposed between the spaces formed by adjoining slabs, the spacing of which is such as to afl'ord a snug iit for the web. The head portion 8 of the strip, which extends at right angles to both sides of the web, is thus adapted to overlie the marginal edges of two adjoining slabs, as shown in Fig. 2. The T-shaped formation of the strip in cross-section gives the same rigidity, so that the same will not easily yield or iieX under the weight of a person stepping thereon. To further guard against the strips yielding or bending under weight applied thereon, the web portions thereof are of a height substantia-lly equal to the thickness of the slabs, so that in applied position the web will rest throughout its length upon the Hoor proper.

Such rigidity of structure further permits the strips to be secured or fastened to the floor proper in an effectivemannerbyiia'st-` ening elements applied to therendsethereof only, and Without electing any bulge or directions and at substantially right anglestothe web vto form the head Aportion 8, thestrip thus having a substantially T-form in cross section. The head end portions are depressed, Aas yat y9, so that the head endf'f nail, Vas l0, will not protrude above the surface-1 plane of the strip in securingithe same toi the `floor yby* drivingthe--nai'l there-AV into. Fig. l5 illustrates how' the head of the lnail lits or is seated in the socket formed 'by the meeting ends ofalinedfstri-ps, one nail securing tivof--ends vvor separatev strips, and

VFig. 3 illustrates how a singleinail serves t0 Vsecure.our-'endsl of -separa-te strips; `The Vendsof thelstrip headsr are also partially mitered, as at c11, so thatthe ends of four intersecting` strips, -as shoWn'in Fig: 3,1YWill be relatively equidistantythus -ormigng an opening ybetween the endsyand'atl the same timel permit f the 1Ahead ,of fthe nail to Vbear up onY substantially equal lp artsoii the strips.

It *Will-'be apparent EVfrom' the 'foregoing' that, by the use ofl the described securing strips and slabs or squares of linoleum or similar floor fabrics, for which thercuttings or remnants -oii'rfslnh fabrics may be used, a very serviceable as v'Well as artistic floor cov- `ering. may be provided.

Having thus described my invention, avhat is claimed :is:

l. A securing strip for Hoor slabs con# sisting of a metallic blank `longitudinallyV folded upon itself to provide a relatively thin and rigid upstanding web: portion, and Y oppositelyl bentrlateral edge margins to pro-V videa head. portion,` the strip'being substantially ofIT-form incross section.

A securing-strip for floor slabs con` 'sisting of a metallic blank longit'udinallyY folded to provide-.al*relatively thin and rigid upstanding web? portion, and edge margins oppositely :bent at substantially right-,angles Ito the Webf` portion .and depressed at their ends, the-strip being offsubstantiallyTeform 'incross section. s Y

'3. Assecuring'strip 'for floor slabs 'consi'sting of fa. f metallic. blank. longitudinally folded to providea relatively. thin and 'rigid upstanding web portiom` and edge margins oppositely bent at substantially rightangles to the f Web: portion, vthe said lmargins lbeing depressed at their ends and their corners 1 mitered, the strip throughout its llength beingl o'fvsubstantially rTr-form in cross sec#V ftion. u l
